I/O interface 430 may represent one or more interfaces and may be any of various types of interfaces configured to couple to and communicate with other devices (e.g., to receive an indication of the status of the PV system from an inverter, to communicate module status to an inverter or other remote device), according to various embodiments. In one embodiment, I/O interface 430 is a bridge chip from a front-side to one or more back-side buses. I/O interface 430 may be coupled to one or more I/O devices 440 via one or more corresponding buses or other interfaces. Examples of I/O devices include storage devices (hard disk (e.g., 440E), optical drive, removable flash drive, storage array, SAN, or an associated controller), network interface devices (e.g., 440A, which may couple to a local or wide-area network), user interface devices (e.g., mouse 440B, keyboard 440C, display monitor 440D) or other devices (e.g., graphics, sound, etc.). In one embodiment, circuitry 400 can be coupled to a network 470 via a network interface device 440A. I/O devices 440 are not limited to the examples listed above. All depicted I/O devices 440 need not be present in all embodiments of circuitry 400.
